Title: Acoustic transducer components
Inventor: SPRECHER ARNOLD FRED JR
IPC: G01F23/28
Filed: 1996-05-10
Granted: 2010-08-24
Abstract: A waveguide suspension device (2) and modular construction for sonic waveguides (4), including a damping element (6) for use with a waveguide (4) that supports a current pulse and results in a torsional or longitudinal strain wave, is also disclosed. The damping element (6) is to prevent the reflection of the sonic strain wave and includes a sleeve (27) surrounding the waveguide and a mechanism (29) for applying pressure on the sleeve (27) so the sleeve (27) exerts pressure on the waveguide (4), thereby gradually dampening the sonic strain wave energy along the length of the waveguide (4) surrounded by the damping element sleeve (27) to prevent reflection of the sonic strain wave. Further, the return conductor (1) placement is determined by measuring system response to provide minimal ringing of the signal received from a pickup coil (13). In addition, the suspension mechanism (2) is used to contain the waveguide thereby avoiding extraneous noise. A bracket (10) is disclosed that facilitates the process of assembly of the waveguide assembly. Also, a local buffer circuit for use with a magnetostrictive transducer is disclosed wherein the magnetostrictive transducer (4) includes a pickup coil (13) and the local buffer circuit includes two diodes (22, 23) in parallel with the pickup coil (13) to clip or short the energy produced in the pickup coil (13) generated by an interrogation pulse, and also includes a common emitter amplifier (24) to reduce the electrical impedance of the pickup coil (13), also in parallel with the pickup coil (13).

Title: Mulching mower deck
Inventor: BENTER DEAN WILLIAM
IPC: A01D34/00
Filed: 1997-12-18
Granted: 2001-08-21
Abstract: A mulching mower deck within which first and second mower blades rotate for cutting grass, having first and second blade chambers positioned adjacent each other and within which respective blades rotate during operation. The first and second blade chambers are generally completely enclosed for generally confining grass clippings within the blade chambers for preventing the clippings from exiting through side or top walls of the mower deck. The first and second blades travel in respective paths which overlap. The first blade is positioned to the right of the second blade with respect to forward operation of the mower deck and travels in a clockwise direction, and said second blade is positioned to the left of the first blade and travels in a counterclockwise direction. An opening is formed between the first and second blade chambers at a location where the blade paths overlap. Edges of said opening are positioned relatively close to the first and second blades near where the blade paths overlap. A flow divider defines the opening and is positioned generally above the location where the blade paths overlap, and extends downwardly from the top wall of the mower deck to a position in relatively close vertical proximity to the rotating blades where the blade paths overlap. The flow divider includes a portion directly in front of where the blade paths overlap, which acts to divide and direct air and clippings to respective blade chambers.

Abstract: A baler for making parallelepiped bales is equipped with a bale ejector or thrower structure including a bale throwing pan supported by a four-bar linkage that is swung upwardly by a hydraulic throwing cylinder. A control valve structure including a solenoid-operated trip valve and a solenoid-operated pressure-relief valve is actuated for effecting pressurization of the throwing cylinder and throwing of a bale in response to a trip switch being closed in response to a trip pedal being rotated by a bale moving rearwardly on the throwing pan as it exits the baler bale chamber, the trip valve when actuated blocking a source of fluid pressure from normal communication with a fluid sump, and the pressure-relief valve when actuated being operable for maintaining the working fluid pressure at a value determined by a variable potentiometer connected in circuit with the solenoid of the pressure relief valve. The pressure of the fluid available for operating the throwing cylinder and, hence, the distance through which a given bale will be thrown, depends on the setting of the relief valve achieved through adjustment of the variable potentiometer. An interlock circuit is provided for preventing actuation of the throwing cylinder in the event that a shield structure, which surrounds the area occupied by the throwing pan, is lifted to an inoperative position, such lifting opening an interlock switch. An interlock relay switch is provided which, when energized, maintains the availability of power to a power port of a timer coupled for receiving a control signal when the trip switch is tripped, the signal acting to change the state of the timer so that it connects power to the trip and pressure-relief valve solenoids for a preset time, the interlock relay switch acting to open the current path to the timer power input port in response to the interlock switch moving to its normally open position in response to the shield structure being raised to a non-working position.

Abstract: It is possible to generate a resonance mode such that a dielectric resonator (20) can be resonated and an electric field vector leaking out from the resonator (20) exists by arranging antennas (22a and 22b) for the resonator (20). When a sample (22) has dielectric anisotropy, the resonance frequency of the resonator (20) varies when the sample (25) or resonator (20) is rotated. The dielectric anisotropy of the sample (25) is found from the variance of the resonance frequency. Thus the dielectric anisotropy of not only a sheet-like sample, but also such a sample as a three-dimensional molded sample can be measured.
